Abstract

The steering sensor unit (1) includes a magnetic wheel (2) having an axis of rotation (A) able to be coupled in rotation with the steering wheel of a motor vehicle, and with a plurality of first and second magnetic poles with opposite polarity, uniformly distributed in alternating manner along an outer peripheral portion (6) thereof; and a Hall-effect detection device (8) fixed to the body of a motor vehicle in a position facing the peripheral portion (6) of the magnetic wheel (2) and cooperating, in use, with the peripheral portion (6) in order to generate at least one output information signal indicating the speed, the number of turns, and the direction of rotation of the steering wheel.
